I Appear to Have a 'Button' Near the Tip of my Nose That Affects the Airflow Between my Nostrils. I'm Guessing That's Not Normal

Suffering a number of issues with my nose, including chronic congestion, heavy sneezing and waking up in most mornings with severe headaches. Last doctor I saw was convinced the headaches were neurological, the nasal symptoms irrelevant. But my nose has never "felt" right, it's particularly large and Roman and properly looking at it I feel a button below the bridge that clicks and affects which nostril I breathe through. Typically, I only breathe through one. Any advice? Does it need attention?
